Kettle Tilly Portrait Of Lord Charles Spencer Churchill Tilly Kettle (1735-1786)

The picture has something of this: portrait, people, wear, jacket, man, retro, musician, leader, music, youth, coat, facial expression, singer, lid, outfit, fashion, military, cravat.
Perhaps it’s a close up of a painting of a man wearing a red and white outfit and holding a black box with a yellow tassel around his neck.
